Summary

Constructed in 1965, this Earth-type dam boasts a height of 52 feet and a length of 2850 feet, with a maximum storage capacity of 15,912 acre-feet and a normal storage level of 9306 acre-feet. The dam's primary purpose is recreation, providing a surface area of 579 acres for outdoor activities while also supporting a drainage area of 10.3 square miles.

Managed by the Mississippi Department of Environmental Quality, Flint Creek Reservoir Dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and hazard potential are closely monitored. Despite being categorized with a high hazard potential, the dam currently maintains a satisfactory condition assessment, last evaluated in February 2020. The dam's spillway, with a width of 4 feet, operates as uncontrolled, allowing for a maximum discharge of 7719 cubic feet per second in cases of excess water flow. With a moderate risk assessment of 3, ongoing risk management measures and emergency action procedures are crucial components of its operation to mitigate potential risks and ensure public safety.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
